NZ Post plans to get rid of more than 700 mail delivery staff

It's confirmed the traditional postie is soon to be extinct. New Zealand post is pushing ahead with plans to get rid of more than 700 mail delivery staff. Letters will eventually be delivered by couriers who currently just drop off parcels. The union has described it as a race to the bottom, using contract workers who don't get the same benefits as employees. NZ Post CEO David Walsh speaks to Lisa Owen.
